Abstract: Postupak pripreme fotopolimernog materijala i sustav uređaja s primjenom u DLP (Digital light processing) 3D printeru uključuju sustav za održavanje stalne razine tekućine (1, 11, 12 i 13), valjak (8) i zasićenu tekućinu (19) u posudi (1) u kojoj se provodi printanje 3D modela (2). Ovaj izum se odnosi na način i cjeloviti postupak pripreme fotopolimernog materijala (4) kod printanja 3D modela (2) na DLP 3D printerima. Gore navedeni elementi sustava čine cjelinu i na taj način rezultiraju najučinkovitijim utjecajem na rješavanju do sada prisutnih tehničkih problema kod 3D printanja DLP tehnologijom.<BR/> <BR/>Primjenom ovog cjelovitog postupka omogućava se veća brzina printanja 3D modela (2), postiže se veća preciznost isprintanih 3D modela (2) te u konačnici utječe na pojeftinjenje izrade 3D modela (2) printanih na DLP 3D tehnologiji. Po ovom izumu, printanje je moguće u kontinuitetu, bez prestanka rada, sa konstantnom ponovljivošću isprintanih 3D modela (2). I ono što naročito ističe prednost ovog izuma je mogućnost kvalitetnog i preciznog printanja 3D modela (2) neograničenih dimenzija.<BR/> <BR/>Primjenom ovog izuma rješavaju se postojeći tehnički problemi kod printanja 3D modela (2) sa DLP tehnologijom, a to su: taloženje pigmenta (6), potreba za miješanjem fotopolimera (4), hlađenje fotopolimera (4) te očuvanje konstantne udaljenosti između projektora (3) i površine fotopolimera (22). Konačni rezultat primjene ovog izuma, a uzevši u obzir i rješavanje prisutnih tehničkih problema, je da izum doprinosi da je printanje 3D modela (2) brže, preciznije, jeftinije i moguće u neograničenim dimenzijama printanja 3D modela (2).The process of preparing the photopolymer material and a system of devices with application in DLP (Digital light processing) 3D printer include a system for maintaining a constant liquid level (1, 11, 12 and 13), a roller (8) and a saturated liquid (19) in the vessel (1) in which 3D model printing is performed (2). The present invention relates to a method and a complete process of preparing a photopolymer material (4) when printing a 3D model (2) on DLP 3D printers. The above elements of the system form a whole unit and thus result in the most effective impact on solving the current technical problems in 3D printing by DLP technology.<BR/><BR/>The application of this complete procedure enables higher speed of printing 3D models (2), achieves higher precision of printed 3D models (2) and ultimately affects the cost of making 3D models (2) printed in DLP 3D technology. According to the present invention, printing is possible continuously, without interruption, with constant repeatability of printed 3D models (2). And what particularly emphasizes the advantage of the present invention is the possibility of quality and accurate printing of 3D models (2) of unlimited dimensions.<BR/><BR/>The application of the present invention solves the existing technical problems when printing 3D models (2) by DLP technology, namely: pigment deposition (6), the need to mix photopolymer (4), cooling the photopolymer (4) and maintaining a constant distance between the projector (3) and photopolymer surface (22). The final result of the application of the present invention, and taking into account the solution of the present technical problems, is that the invention contributes to the printing of 3D models (2) faster, more accurate, cheaper and possible in unlimited dimensions of printing 3D models (2).
